SUCKEE--ROD REMOVER.

Application filed December 28, 1322.

To all whom it may camera:

Be it known that I, ERNEST PAGE, a citizen of the United States, residing at W'irt, in the county of* Carter and State of Oklahoma, have invented certain new and usefnl Improvements in Sucker-Rod Removers; and do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. A

The invention has for its primary object the provison of a tool whereby a broken sucker rod may be removed from a well Whether the break is at a joint or intermediate the joints, the tool embodying a latch to postively engage the shoulder when the suclier rod breaks at a joint and embodying a friction grip to engage the sucker rod when the break is at a point between the joints.

Other objects and advantages will be apparent and Suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodinlent of the invention it is to be understood that in adapting the saine to meet diflerent conditions and requirements, Varions changes in the form, proportion and mnor details of constrnction may be resorted to .without departing from the nature of the invention.

Referring to the accompanyng drawings forining a part of the application,

Fignre l is a, sectional view of the tool,

l igure 2 is a detail sectional view showing the latch which is adapted to engage a shoulder,

Figure 3 is a detail section of the friction p,

Figura l is a horizontal section on the line 4-4 of Figure 3, and

Figure 5 is a detail perspective view of the friction grip, the parts being separated.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The tool embodies a casing 1 which 'may be a length of pipe of required size. The casing 1 contains the elements for engaging the sucker rod or other analogous part to be removed from a well. An Opening 2 is formed in a side of the casing 1 and a latch V 3 is pivoted at one end to a side of thecasing and is adapted to swing across the Opening 2 and have its onter marglnal portion en* gage and rest upon the part of the caslng Serial No. 609,450.

bordering upon the lower end of the Opening The outer marginal portion of the latch 3 is rabbeted, as indicated at l, to receive the part of the caslng upon which it rests, so that the shoulder formed by the rabbet en gages the inner wall of the casing and prevents outward or lateral displacement of the latch 'When under Stress, as when lifting a sucker rod or like part. It is observed that the latch 3 is located wholly at one side of the casing 1 and extende therein suniciently far to engage the shoulder of a sucker rod When the break is at the joint,

The friction grip for engaging the sucker rod When the break is intermediate the joint,

comprises a head 5, a gripping element or jaw 6 in line with a side of the hea d 5 and extending longitudinally thereof from one end. The gripping element or jaw 6 tapers thronghout its length, being of a maximum thickness at its free end. The inner face of the gripping element or jaw 6 s formed in its length with a half-round groove 7 and the extremty of the aw is beveled. A complemental jaw or gripping element 8 is of uniform thickness throughout and is provided at its inner end with a lateral extension 9.

The inner face of the jaw 8 is provided with a half-round groove 10 which fiares at the outer end* of the jaw. A wedge 11 is disposed between the fiXed jaw 6 and the movable jaw 8 and its outer side is formed with a half-round projection 1.4 to match the half-round groove 7 of the jaw 6 and its inner face is formed with a half-round groove 13 to match the half-round groove 10 of the loose or m'ovable aw 8. The outer edge of the wedge 11 is beveled ontwardly from the groove 13 and with the beveled ends of the jaws 6 and 8 direct the end of a sucker rod to be recovered into the Opening formed by the matching half-round grooves 10 and 12. These grooves are corru 'ated or toothed to insnre a firm grip upon the sucker rod or other implement to be recovered from a well.

'While it is preferred to embody both the latch 3 and the friction grip in a single tool, thereby adapting the sarne for recovering shouldered or plain rods, nevertheless in practice the. tool may contain either the Downward displacelnent of the Wedge ll and jaw 8 is prevented by the Wedge form of the jaw 6 as shown most cleariy n Fgure l. An expansible helical Spring 15 s intei'posed be tWeen the head 5 and the Upper end of the jaw 8 to insure holding the parts 8 and 11 at the limit of their downward movement. The j aw 8 and Wedge 11 have :x limited Vertical movement to admitof their separation that a rod 01' tool may be received heeen them and gripped by a wedging action.

hat is olaimed is:

1. In a tool of the oharacter specified', a i'ietion' gri p oomprising a head, a jaw at one Side of the head and in line therewith and increasing in thiekness towards its outer end, a complemental movahle jaw, and en intermediate Wedge between the two jews 2. In a tool of the character sp*eeified, e 'iotion gi'ip comprisirrg a head, a jaw at one side of the head and in line therewith and inoreasing in thic'kness towar'ds its outer end, a* oomplemehtal movabie jaw, and en interme'di ate Wedge between the' two jaws, the fixed jaW having its innei face iongitudh nafly grooi'ed and the Wedge having e correspohding pi'ojection upon its outer side, and the opposing faces of the Wedge and movahie j aW being correspondingly grooved.

3'. A tool of the charaoter specified includng a friotion grip having a head, a' at one side of the head and in line thereWith and ncreasing in thiokness toward its outer end, a complemental jew, en intermediate Wedge between the two jawathe fiXed jew Leving its DDGY fa* e iohgitudinafly grooved and the Wedge heving a oorrespondng projeotion upon outer side, the opposing aees of the* Wedge and inovable jaw being correspondingly grooved and EL Coil Spring interposed between the head and the Upper end of the movahle 'jaw to hold the jeW and wed 'e at the iimit of their downward moveinent.

In testimony whereof I LffiX my signeture in presenco of t r-:0 Witnesses.
